Problems solved by technology

Furthermore, the herbicides exhibit weak points (zero effect) against specific species of harmful plants.
However, the combined use of a plurality of active compounds does not infrequently lead to phenomena

Embodiment Construction

[0018]Preferred components (A) are in each case per se

[0019]glufosinate and its salts,

[0020]L-glufosinate and its salts and

[0021]bialaphos and its salts.

[0022]Particularly preferred components (A) are in each case per se

[0023]glufosinate-ammonium (A1.1),

[0024]L-glufosinate-ammonium (A1.2) and

[0025]bialaphos-sodium (A1.3).

[0026]Compounds of the formula (B1) in which the substituent R is CO2H (i.e. carboxylic acid function), are taken to be those compounds which bind to the active site of a plant enzyme or of a receptor and thereby bring about a herbicidal effect on the plant. Other compounds of the formula (B1) in which the substituent R is a group which can be converted within plants or the environment into a carboxylic acid function (i.e. CO2H) produce a similar herbicidal effect and are likewise encompassed by the present invention. Consequently, within the context of the present invention, a herbicidally active derivative is understood as meaning in particular salts, esters, carb...

Abstract

The invention provides herbicide combinations and the use of herbicide combinations for controlling harmful plants in rice crops wherein the herbicide combination in question comprises
(A) a herbicide from the group of the compounds of the formula (A1)
    • in which Z represents hydroxyl, —NHCH(CH3)CONHCH(CH3)COOH or —NHCH(CH3)CONHCH[CH2CH(CH3)2]COOH,
or an ester or salt thereof, and
(B) a herbicide of the formula (B1)
in which X represents N or CH and R represents CO2H or a herbicidally active derivative thereof, and the rice crops are tolerant, if appropriate in the presence of safeners, to the herbicides (A) and (B) present in the combination.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to European Application 10163615.7 filed May 21, 2010, the contents of which are incorporated by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]The invention relates to the field of crop protection compositions which can be used against harmful plants in tolerant or resistant crops of rice and comprise, as herbicidally active compounds, a combination of two or more herbicides.[0004]2. Description of Related Art[0005]The introduction of tolerant or resistant rice varieties and rice lines, in particular mutagenic or transgenic rice varieties and rice lines, adds novel active compounds which per se are not selective in conventional rice varieties, to the conventional weed control system. The active compounds are, for example, the known broad-spectrum herbicides such as glyphosate, sulfosate, glufosinate, bilanafos (=bialaphos) and imidazolinone herbicides, which can now be employed i...
